Application filed May 3,

gld-allcv hom it may concern it known that I, PH I LIP.PRINGLE, of the town of Lipton, in t e Province of Saskatchewan, Canada," have invented certain new and useful Im rovements in- Valve- Spring Lifters, of which the following is the specification. i

The invention relates to improvements in the principal object of the invention is to provide an easily constructed and. easily operated device for simultaneously lifting the valve springs an automobile engine and thereby permit-' tingof the releasing of the valves for grindingor other such purposes.

A further ob ect of the invention is to construct the appliance so that it can be readily attached or..removed and can be positively relied upon not only to simultaneously raise the valve springs but to lock them in the raised position,

With the above general objects in view the invention consists essentially in the arrangement and construction of parts hereinafter described and later pointing had to the accompanying drawing in which v Figure 1 represents a side view of an automobile engine showing my invention' 'applied thereon and in the non-operating or lowermost position.

shortly described, 'is'arranged to raise all valve springs together and lock them when raised. In this way I save considerable time and labor and give one the free use of his hands for valve grinding or'other .purposes.

Referring now to the drawings Irepresents the valve spring chamber provided in the side of the engine and which is customarlly covered over by a releasable closure plate (not shown). Centrally of the chamber, an outwardly extending fastening pin 2 is provided, this pin having its outer end threaded and provided with a nut and being utilized to hold the ordinary closure plate in closed position."

The chamber push rods 4, the valve' springs 5 and the valve springseats or cups 6, the cups engaging removable pins '7 passing through the stems.

The above parts are of ordinary construction and I have not accordingly considered it necessary to give a detailed description of springs operate to hold the valve stems normally down and engaged with the push rods, it being understood that the'seating and'unseating of the valves is governed by suitable cams control-, hug the push'rods. In practice it is quite often necessary to grind the valve or the valve seats and at such a time one has to remove the pins 7 in order to release the valves. This is done by bodily raising the cups or valve spring seats 6 against the action of thesprings and clear of the pins. My lifterwhich is designed to accomplish this workis now descrlbed in detail. I i

8 represents a lifting bar of angle iron cross section and presenting a horizontal wing 9 and a vertical wing 10. The horizontal wing is of such a'length that it will go freely within the opening 1 while the vertical wing is somewhat longer so that it will seat outside the opening at the ends.

The horizontal wing 9 is provided with a plurality of slots 11, the slots being spaced apart to correspond with the valve stems or in other words when the lifting plate is houses the valv stems 3, the

inserted the slots receive the valve stems,

The slots completely cross upwardly a short 10, the extensions spanning them. the Wing 9 and extend being shown at, 11'. are gouged out as indicated at 12 and 13 to form seats for the cups as later expla ned,

he edges "of the slots Centrally of its length the lifting plate is fitted with a cross slot 14 which extends completely across the horizontal. wing and well up into the vertical wing terminating at 14. 15 represents a vertically disposed guide flange extending downwardly from one of the edges of the latter slot. 16 represents a tube designed to receive the fastening pin 2 and of a length such that the 7 The eccentric disk and riding plate are constructedsuch that when the diskis in the position as shown in Fig. 1 the wing 9'is spanning all the valve stems and with the rvalve spring seats or cups mediately s"ay directly over the ositioned imabove the said wing, that is to gouged out or cut away parts12 and 13 of the slots.

The riding plate i'sfitted with portions 19'iwhich- -overhangthe disk and prevent head 17 .a revolution which action bodily raises the the lifting plate from canting under the -action'of the springs when the device is in en'one deslres to ralse the valves use. he applies a wrench or similartool to the of the tube and turns the disk half lifting plate-a distance e ualto the eccentric throw of the disk. he lifting plate in rising carries with it the valve spring seats. and frees the valves so that they can be readily" raised and also exposes the pins can .be easily. withdrawn 1f 7 so that they it is desired to remove the valves. 7

Here it will be observed that in the raised position of the lifting plate it becomes automatically locked, this occurring when" the disk reaches what might be termed the dead center position. Accordingly one is entirely free to use both hands for valve grinding or other such purposes.

In actual practice, particularly from the standpoint of shipping and marketing, it would be desirabe to have the tube and ing plate presenting disk disposed neath the riding eccentric disk arranged so that they cannot be removed from the lifting plate. Any suitable arrangement can be provided for this purpose, it being only necessary that the movement of the parts be not interfered with when the lifter is in use. I

What I claim as my invention is z.-

1. A valve spring lifter comprising a lifting plate adapted to engage the under'sides of a plurality of valve spring seats, and an eccentric disposed with the peripheral edge thereof having lifting engagement with said plate and designed in the rotation of the eccentric to bodily raise the plate through such engagement and simultaneously lift the valve spring seats.

2. A valve spring lifter comprising a lifta horizontal and a' vertical wing and having the horizontal wing slotted at intervals to admit the, stems of the valves, a plate constituting a riding plate secured on one side of thevertical wing of said lifting plate, and an eccentric I of the eccentric to elevate the said riding plate and the lifting plate.

3. A valve spring lifter comprising a lifting plate presenting a horizontal and a vertical wing and having the horizontal wing slotted at intervals to admit the stems of the valves, a riding plate located centrally of the vertical wing, an eccentric disk positioned adjacent to the vertical wing and engaging the riding plate, a centering tube extending from the disk and extending into and through the vertical wing, said vertical being slotted to wing and horizontal wing allow of the movement of in the turning of the disk.

-l. A valve spring lifter comprising a lifting plate, a riding plate, and ,a rotatable eccentrically mounted member disposed beplate and in engagement therewith and designed, in the rotation of said member to elevate said lifting plate.
